Finally

The BBC has an article about the latest in the search for the missing plane:

Search teams have begun using a towed pinger locator (illustration) to hunt for the black box of missing Malaysia Airlines Flight MH370. Two ships with locator capabilities are searching a 150 mile underwater path, in the hope of recovering the plane's data recorder.
Up to fourteen planes and nine ships were due to take part in the search.
The battery-powered pingers on the plane's black box stop transmitting about thirty days after a crash, giving the searchers now perhaps only a few days to locate it.
Angus Houston, head of the Joint Agencies Coordination Centre (JACC) leading the search, said that two ships had "commenced the sub-surface search for emissions from the black box pinger".
Australia naval vessel Ocean Shield was using a towed pinger locator loaned by the US Navy, while HMS Echo, which had similar capabilities, was also searching.
Officials said there was "some hope" the locators would be able to find the black box.
"The two ships will search a single 240km track, converging on each other," Air Chief Marshal Houston, who is retired, said. ACM Houston said that the area had been picked on the basis of analysis of the satellite data. He pointed out that this data was continuing to be refined, but the current search was based on the "best data that is available". Given the progress in data evaluation and calculation, "there is some hope we will find the aircraft in the area we are searching", he added.
The two ships will be moving at reduced speeds, of around three knots, in their attempt to detect any signal from the pinger. Commodore Peter Leavy, the commander of Joint Task Force 658, said that search operations generally preferred to use "physical evidence" and "drift modeling" to locate a plane. However, "no hard evidence has been found to date so we have made the decision to search a sub-surface area on which the analysis has predicted MH370 is likely to have flown," he said.
In a statement, JACC said up to ten military planes, four civilian planes and nine ships would be deployed in the search efforts.
The focus is on a search area of about 84,000 square miles, a thousand miles north west of Perth, Australia.
Fair weather was forecast for Friday, with visibility of around six miles, JACC said.
Meeting staff involved in the search, Australian Prime Minister Tony Abbott said: "It is probably the most difficult search that's ever been mounted. A large aircraft seems like something that would be easy enough to locate, but a large aircraft that all but disappeared and disappeared into inaccessible oceans is an extraordinary, extraordinary challenge that you're faced with."
ACM Houston said there was still a "great possibility of finding something on the surface of the ocean. There's lots of things in aircraft that float," he said, citing previous searches where life jackets from planes were found.

Rico says he hopes the pinger works...
